Arac variant, in which the residue at position 61 was replaced with an alanine (rac61a), was synthesized. wild-type rac and rac61a were incubated separately with vopc. to obtain data to support that vopc modifies rac at residue 61, the samples should be analyzed for the presence of which compound? co2 nh3 o2 h2s

distance, luminosity, brightness, radius, chemical composition, and temperature

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
